2018 LaCrosse

The Buick LaCrosse has been given substantial drivetrain updates for 2018. The third-generation LaCrosse now comes standard with a 2.5L 4-cylinder light hybrid engine that Buick calls 'eAssist'. A new 9-speed automatic transmission has been introduced to pair with the optional V6 engine while all-wheel drive is now offered to V6-equipped Premium and Essence models.
